The press release accompanying the release emphasizes how little power these new cards draw:īoth the ATI Radeon HD 4670 and ATI Radeon HD 4650 deliver substantial gaming horsepower with minimal power draw – the ATI Radeon HD 4670 operating at under 60 watts and the ATI Radeon HD 4650 operating under 50 watts under full load – eliminating the need for additional power connectors and making installation a cinch.īuilt with efficiency, scalability and performance in mind, the ATI Radeon HD 4600 series sets a new performance-per-watt standard for mainstream graphics products, thanks to the enhanced bandwidth of DDR3, new power management capabilities that provide greater performance and efficiency, and 55nm technology. The HD Graphics 4600 can be found on dual- and quad-core Haswell models in the 37 - 57 Watt TDP range.Note: A version of the HD 4670 with 1GB of memory is scheduled to be released later this month. Thus, the HD 4600 not only matches some dedicated GPUs such as the GeForce GT 620M/630M, but also competes with the fastest integrated AMD GPUs like the Radeon HD 8650G.ĭue to the 22nm 3D Tri-Gate production process, power consumption should be relatively low. This performance boost is achieved by architectural improvements and an increased number of execution units: The GT2 version integrates 20 EUs, compared to 16 EUs for the old HD 4000. In our gaming benchmarks, however, the improvement was only about 30 percent. It also features an improved decoder for 4K videos and the fast Quick Sync encoder.Īccording to Intel benchmarks in 3DMark 11, the HD Graphics 4600 will be up to 60 percent faster than the previous HD 4000. The GPU supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. In comparison to the HD 4000, the graphics core has been modified extensively. The base clock can be automatically overclocked using Turbo Boost technology.ĭepending on the processor model, the base and turbo clock rates may differ greatly resulting in varying graphics performance between CPU models. The Intel HD Graphics 4600 (GT2) is a processor graphics card included in some of the Haswell processors of 2013.
